Hi all,
I'm having a few problems with a black Macbook (Intel Core Duo 2GHz) I've been given (I was warned of the faults) and I hope someone will be able to point me in the right direction. The warranty on the machine has long since expired. The hard drive was broken, but I've swapped in one from another Macbook, which works fine.
1. When I hit the power button on the machine, there's a momentary flash from the LCD, then the machine goes dead. This happens every time. To get the machine to start up, I now have to hold down the power button for 10 seconds until the light on the front starts flashing and the Macbook emits a loud beep. Right before I get the Apple logo when the machine boots, I get a flashing folder icon with a question mark in it. This lasts for only 1 second, then the machine starts as normal.
2. Probably related to point 1, this problem occurs when the machine is in sleep mode with the lid shut. When I lift the lid and the LCD comes on I can see my desktop for about a second before the machine abruptly switches itself off.
3. Once in the OS (Leopard), the fan goes nuts and hovers around 6000RPM all the time. I've followed various bits of advice regarding this, including using Activity Monitor to track down rogue processes (nothing above 3% CPU usage), print jobs (none), etc. The fan is sitting at a healthy 41 degrees Celcius (105 Fahrenheit). I've downloaded smcFanControl, but for some reason I can't get this to run. I double-click the icon, but nothing happens -- weird. I don't really think manually controlling the fan speed addresses the root cause anyway.
I've tried an SMC reset for the fan problem, but this did not solve the problem. I've tried booting the machine in safe mode, but this had no effect either.
Do I have a borked logic board?
Thanks,
Rob
